Heterogeneous distribution of pectin epitopes and calcium in different pit types of four angiosperm species
Download2011
Intervessel pits act as safety valves that prevent the spread of xylem embolism. Pectin–calcium crosslinks within the pit membrane have been proposed to affect xylem vulnerability to cavitation. However, as the chemical composition of pit membranes is poorly understood, this hypothesis has not...

We tested two hypotheses for how vessel evolution in angiosperms influenced xylem function. First, the transition to vessels decreased resistance to flow—often considered the driving force for their evolution. Second, the transition to vessels compromised safety from cavitation—a constraint...

Two structure‐function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low‐resistance torus‐margo pits. Second, vesselless wood ought to be exceptionally safe from...
